tiny cards scoring
I don't know where to ask a question about Tiny Cards. I have completed quite a few lessons but my score (a long yellow line showing completion) isn't always recorded. I don't understand the system. I often do the same lesson several times and yet, no yellow line.
I am still hoping to hear from somebody in the Duolingo technical team -- is there one? I just finished tinycards adverbs -- done it more than once. No yellow line, no indication that I ever completed those four cards plus the little wrench on the side. I enjoy doing them. They are helpful. But don't have a clue what the scoring strategy is.
